(bug) Agents don't receive uploaded image attachments

[ashrafchowdury]

When a user uploads an image attachment in the chat interface and asks the agent about it, the agent replies that it hasn't received the image. The attachment never reaches the agent's context.

Steps to reproduce:

1. Open a conversation in the production environment.
2. Upload an image file as an attachment.
3. Ask the agent a question about the image (e.g., "What's in this image?").
4. Observe the agent's response — it states it hasn't received any image.

Environment:

• Production environment
• Models tested: deepseek-v4-flash and gpt-5-luna
• Both models exhibited the same behavior

Expected behavior: The agent should receive the uploaded image and be able to reference it in responses.

@ashrafchowdury please add preliminary analysis of the issue if reproduced locally. It helps a lot and removes overhead (since you already have the issue so you can just ask the agent about the session id what happened).

Side question, does this happen with sol for instance? or larger models?

I use image attachements a lot without issue

It's in production; all the issues I create are from production. I mention specifically if it's found locally
